rebeljake69 **Update**

Still no progress. I guess i've just been dreading the rebuild process and letting this part stop me. I'm not sure if i should even bother with taking it to the machine shop at this point or if i should just buy a new one. I haven't taken it to the shop to get any quotes or know of the general cost to get something like this done but I know that i've done more bad than good with trying to get the valve guides out. The positive to buying new is obviously everything would be new short of the crank and cam in the engine. Downside would be the 450 dollar price tag. But if i'm going to have to spend 200 on a machine shop for a used part that seems to be very worn, I'd pay the extra to have new. Even though i'd still have to go to the machine shop to have the guides pressed into the new cylinder head. I don't know the best route, i'm definitely on the fences about it and this is the last piece of the puzzle before the long journey of putting this SOB back together.

Well that's good to know. I will just end up taking it to a local machine shop and having them do it. I hope that they don't charge me an arm and a leg.. Haha

If you want it port and polished then, I'd look at a shop like EHS racing or similar.
First I tried drilling them out and it may have done more damage than good. So then I tried using the old valve and a socket and a rubber mallet and couldn't get them to move. The oven is currently heating up with new guides in the freezer. I'm assuming I try putting the valve with a rubber mallet and see if that will work with the heat. Another thing i noticed was the new valves didn't slide into the new guides. I'm assuming the guides need to be heated with the valves cooled but not sure. I hope that's the case anyways.. Haha I bought all of the parts at the same time on partzilla so they should be right but idk.

rebeljake69 Okay so I apologize for not replying or anything of that sort. Classes started back and i took a minor needed vacation to the beach with some family. But I haven't made any progress, I have attempted to remove the valve guides but have been quite unsuccessful using methods i've found on the web via youtube. I don't feel comfortable enough using brute force because if I screw up and break something, i'm out 450 more dollars. I'm basically to the point of taking it to some sort of shop and seeing if they can remove the guides, put mine in, and give it back to me. But i'm not sure the kind of shop to do that. I've never had to put anything in a shop because i've been able to do it myself but this one has stumped me. If anyone has any ideas of how i may be able to remove them or just reference me to the type of shop i need to be looking for, (machine shop, motor repair, four wheeler shop, honda), I would greatly appreciate any guidance at this point!

M_Quick Well you will for sure want to replace those valves. The cylinder head is probably okay, you just need to replace the valve guides. Now from what I remember your cylinder it's self needs replaced but, it's alot cheaper than the head!

Yeah it will be tough, but i should be able to get it done. I just can't get past the whole buying a whole $460 cylinder case just for those little cracks and spending 140 on valves because they are just barely bent. Aside from that, I could have it up and running very soon. Haha

rebeljake69 Finally got the motor split using that clutch holder. Thank you Kubi! figured out that i'm really glad i split the motor because during the slow process of splitting them apart, sooooo much metal came out of where all of the gears are and lodged into places that i'd never get out had i not split the motor. My garage is the messiest it will probably ever be with everything thrown around and parts everywhere. Looking at everything on the floor, it's so intimidating thinking about putting it back together. I hope that when i get to certain parts, my memory will spark but first i have to buy parts and get them, then clean the motor. Once it's clean, I'll begin piecing it back together one baby step at a time. Until then enjoy these pictures which include my disaster of a garage and the trash that came from inside my motor.
